THE PLATINIUM-RHODIUM ALLOY CATHODE CATALYST FOR LOW TEMPERATURE TYPE FUEL CELL

摘要

The invention platinum obtained that, by mixing and reduction of the platinum and rhodium in the proper molar ratio on the low-temperature type fuel cell, the anode catalyst material relates to low-temperature fuel cell comprising a cathode made of a cathode catalyst, and the catalyst using rhodium alloy .; Platinum according to the invention-rhodium alloy catalyst because of the excellent methanol oxidation activity, as well as to prevent the cathode poisoning by carbon monoxide caused by the incomplete oxidation of the cross-over of methanol having excellent oxygen reduction activity than conventional platinum as such, it can be used as a low temperature type fuel cell, the anode catalyst of the usage rate and stability of the catalyst performance and increased efficiency.
